在下面的代码中,谷歌地图总是只显示巴黎而不显示输入的位置。
在下面的表单元素中,我正在调用 javascript showAddress(location) 函数。
HTML正文:
<body onload="loadDefaultMap()" onunload="GUnload()">
<form action="#" method="post" onsubmit="showAddress(this.address.value); return false">
<input type="text" name="address" size="40" value="Paris"/>
<input type="submit"/>
</form>
<div id="map" style="width:500px;height:400px"></div>
</body>
脚本:
<script type="text/javascript">
function loadDefaultMap(){
if(GBrowserIsCompatible()){
var center = new GLatLng(48.85661, 2.35222); //Paris
var map = new GMap2(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
map.setCenter(center,15);
geoCoder = new GClientGeocoder(); // this will render the map on th bases of address entered
var marker = new GMarker(center, {draggable: true});
map.addOverlay(marker);
GEvent.addListener(marker, "dragend", function() {
var point = marker.getPoint();
map.panTo(point);
});
GEvent.addListener(map, "moveend", function() {
map.clearOverlays();
var center = map.getCenter();
var marker = new GMarker(center, {draggable: true});
map.addOverlay(marker);
GEvent.addListener(marker, "dragend", function() {
var point =marker.getPoint();
map.panTo(point);
});
});
}
}
function showAddress(address){
var map = new GMap2(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
if(geoCoder){
geoCoder.getLatLng(address, function(point){
if(!point){
alert('Location Not Available');
}else{
map.clearOverlays();
map.setCenter(point,15);
var marker = new GMarker(address, {draggable: true});
map.addOverlay(marker);
}
})
}
}
</script>
提前致谢 :)
